Got one of those newfangled BB386EVO bikes and a fancy new Shimano drivetrain? Wishbone’s new conversion bottom bracket will make their 24mm spindle fit just fine.
Designed for press fit applications with a 46mm frame ID and 86.5mm width (aka BB386EVO), they reduce the hole down to accommodate Shimano and SRAM GXP cranksets, as well as any other brand using a standard 24mm diameter spindle. It rolls with G5 Si3N4 ceramic bearings, and the shell and end caps are 6061-T6 alloy. The two pieces thread together, creating a more solid unit that should reduce any play or creaking, potentially making it a good fix for frames or bearings that might be showing a bit of wear.
Claimed weight is 119g and it comes in gold, red, green, black and blue. Be sure to order either the Shimano (straight 24mm) or GXP (24mm to 22mm) model.
